Let me try this again, just in case I was being ambiguous before.
I am not suggesting that all draw abilities be made CBI abilities. What I am saying is this, once an instant ability, such as a draw ability, has been completed, it cannot be interrupted.
While doing this, your opponent is being specifically allowed to negate it before it happens. The problem with draw/search abilities being negated is that while I make no indictment against any players here, there is always the temptation for a player to be less than honest about replacing cards. Especially when considering cards like Search/False Peace, where your opponent has no knowledge of the card you searched for, there is no way that your opponent can prove that you put the exact card you got from the search/draw back into your deck.
Secondly, and IMO more importantly, is that as it currently exists, there are rules loopholes that allow for abuse of certain types of cards, eg. Foolish Advice, that allowing you to go back and negate an instant ability after it is completed grants more power that card, making it of a higher class than other cards. And in that regard, your not playing Redemption, your exploiting a rules loophole.
